Parkinsonian disorders and other neurological conditions such as stroke can be associated with excessive drooling, also known as sialorrhea or hypersalivation. Drooling may cause significant complications including dental problems, chapped lips, or dehydration and affect the quality of life.
Treatment options for drooling include oral medications such as Robinul or Scopolamine patch, but these may be limited by side effects including sedation, urinary problems or blurring of vision.
Botox injections into the glands that produce saliva are highly effective in reducing drooling. Injections are repeated in 3-6 months depending on the duration of effect. An ultrasound machine is typically used to identify the location of the salivary glands for accurate injection.
